HEATING APPARATUS Application filed June 21,

i This invention relates to certain novel improvements in heating apparatus and has for its principal object the provision of an improved construction of this character which 5 Will be highly eflicient in use and economical in installation and manufacture.

' It is among the objects of my invention to provide a heating apparatus which will be constructed in a manner so as to provide'an 19 effective circulation of the air of the room or.

the like being heated by the apparatus.

Another object of the invention is to provide a heating apparatus in which the heating element will be arranged so that it may be disposed exteriorly of the confines of the room or the like with which it is associated.

A further objectof the invention is to arrange the device so that a register may be provided therein which will be connected by a duct that may be expeditiously installed.

Other objects will appear hereinafter. V

The invention consists in the novel combination and arrangement of parts to be hereinafter described and claimed.

The invention will be best understood by reference to the accompanying drawings, showing the preferred form of construction and in which:

Fig. 1 is a vertical sectional fragmental view of a building construction depicting a room with which my improved heating ar-. rangement is associated;

Fig. 2 is a sectional view taken substan r tially on the line 2-2 on Fig. 1;

" Fig. 3 is a plan view of the portion of the apparatus at the opposite end of the duct from the apparatus depicted in Fig. 2; and Fig. 4 is a detail view of a register employed 40 in the invention. V

In the accompanying drawings wherein I have illustrated a preferred form of construction for my inventionlO indicates a typical joist structure and 11 indicates the exterior wall of a building construction which in the present instance is formed from brick a1- 1929. Serial No. 372,778.

though it is to be understood that analogous building materials might be employed without departing from the purview of my invention. A typical floor 12 is arranged so as to extend transversely of the joist structure 10 and in the manner well understood in the art a wall structure generically indicated by 13 is arranged parallel to but in spaced relation with the wall 11 and in this manner the room l'cis defined between the walls 11 and 13.

In the Wall 11 in the portion thereof disposed toward the room 1 1 and in the section extending upwardly from the floor 12 I pro vide a recess 15. Preferably the recess 15 has a lining 16 of a suitable metallic material provided therein although if desired this metallic lining might be dispensed with but I have found that such a lining is conductive to superior results.

In the present instance I show a steam radiator 17 in the recess 15 which has the usual steam supply pipe associated therewith so as to supply heat thereto in order that the radiator may be heated to cause heat to radiate therefrom. While I preferably employ a steam radiator it is to be understood that other heating elements might be substituted therefor without departing from the spirit and scope of my invention. Arranged over the front side of the recess 15 in front of the radiator 17 is a metallic plate 18. This plate 18 is intended to close the open side of the recess 15 disposed toward the room 1 1 and may be retained in position in any desired manner. In the upper portion of'the plate 18 a grille 19 is provided which includes a frame 27 which may be integral with the plate 18 or separate therefrom and secured to the plate 18 in any suitable manner such as by welding. Mounted in the frame 27 in any approved manner is a plate 36in which a plurality of openings 33 are provided. It is to be understood that while I have shown this grille construction as being a separate member from the plate 18 the same might be l H lll formed as a unitary part of said plate 18 without departing from the purview of the invention.

In the floor 12 adjacent the wall 13 I provide an openin 20. A register construction 21 of any approved form is disposed over this opening 20 and as is well understood the register construction 21 is provided with a plurality of openings. In the present in stance the register 21 includes a frame 27 which is seated on the floor 12 around the opening 20 and which includes intersecting ortions 34 which define a grate. Supported by the frame 27 on rods 35 is a plurality of pivotally mounted slats 28 which are operable by a sector 29 so as to be moved into open and closed position. It is understood that the construction of this register 21 may be of any approved type that will control the flow of air therethrough into the duct 22. The slats 28 in the present instance, are connected to lip portions 30 which are provided on a slide bar 31. The sector 29 is mounted on an extension 32 of one'of the rods 35 as shown in Fig. 3.

In order to connect the register construction 21 with the recess 15 I provide a suitable pipe structure or duct 22 which at one end has an upwardly extending portion 23 that fits below the register construction 21, The opposite end of the duct 22 is provided with an upwardly extending portion 24 that is connected to a flange 25 provided around an opening 26 in the lower wall of the recess 15.

It is manifest that the grille construction 19 is arranged at a higher horizontal level than the register construction 21. In addition to this the recess 15 will be heated by heat radiated from the radiator 17. Therefore, cool air will be drawn in through the register construction 21 and will pass through the duct 22 and the opening 26 over the radiator 17 so as to be heated thereby and will pass out into the room through the grille construction 19. This will obviously create an effective circulation of air within the room which will obviously be highly advantageous and conductive to effective heating and ventilation.

\Vhile I have illustrated and described the preferred form of construction for carrying my invention into effect, this is capable of variation and modification, without departing from the spirit of the invention. I, therefore, do not wish to be limited to the precise details of construction set forth, but desire to avail myself of such variations and modifications as come within the scope of the appended claims.

Having thus described my invention what I claim as new and desire to protect by Letters Patent is:

1. In combination with a room having a recess formed in one wall thereof, a heating element in said recess, a duct extending across said room exteriorly of the confines thereof, means providing a register construction at one end of said duct, the opposite end of said duct opening into said recess, and means including a plate member extending across said recess at the face thereof, said last-named means including a perforated member extended across the upper portion of said recess providing a grille construction whereby air introduced into said recess may escape therefrom.

2. In combination with a room having a recess in one wall thereof, a heating element arranged in said recess, said room having an opening in the floor thereof, a register construction disposed to close said opening, a duct extending from said register construction to the lower end of said recess whereby air introduced into said duct through said register construction will pass into said recess for movement over said heating element, and means including a plate disposed over the front side of said recess, said last-named means including a portion providing a grille construction whereby the air introduced into said recess will be confined by said plate to pass over said heating element prior to passage through said grille construction.

3. In combination with a room having a recess in one wall thereof, a lining for said recess, said recess having an opening in the lower wall thereof, a heating element arranged in said recess over said opening, the floor of said room having an opening therein adjacent the wall opposite the wall having said recess there in, means providing a register construction for closing said last named opening, a duct extended between the joists supporting said floor construction from said register construction in said second named opening to the opening in the lower wall of said recess where by air picked up at the register end of said duct will pass therethrough into said recess, and means for directing said air through said recess over said heating element, said last named means including a grille construction therein in the upper portion thereof whereby said air may escape from said recess after passage over said heating element.

4. In combination with a room having a recess in one wall thereof a lining for said recess, said recess having an opening in the lower wall thereof, a heating element arranged in said recess over said opening, the floor of said room having an opening therein adjacent the wall opposite the wall having said recess therein, means providing a register construction for closing said last named opening, a duct extended between the joists supporting said floor construction from said register construction in said second named opening to the opening in the lower wall of said recess whereby air picked up at the register end of said duct will pass therethrough into said recess, means including a plate disposed over the front side of said recess for directing the air introduced into said recess over said heating element, said lastnamed means including a grille construction adjacent the upper end thereof whereby air passed over said heating element may pass through said grille construction into said room.

In testimony whereof I afiix my signature.
